This article explains how to use Radians to convert from degrees to radians.

On the Grasshopper, it is represented by either of the two above.

Converting from angular degrees to radians

Radians allows you to convert from angular degrees to radians (rad).

Enter a number in degrees into the Radians(D).

Initially, we input 180.

Then, the original value was 180 degrees, but it was output as Pi and changed to radians.

Next, the number to be entered was 90.

Then, 0.5*Pi was displayed and 0.5 x Pi was output.

When the number was set to 45, a decimal number of 0.785398 was output.

As you can see, in some cases, Pi is displayed without using Pi.

Numerical values can also be entered directly into Radians.

To enter a single number, right-click on the Radians(D) and select Set Number.

Then, enter any number and click “Commit changes.

In this case, we entered 180.

The result is a Pi output with 180 degrees converted to radians.

As you can see, you can input directly into Radians.

Multiple numbers can also be entered directly.

To do so, select Set Multiple Numbers.

Then, enter multiple arbitrary numbers and click “Commit changes.

As you can see, multiple numbers can now be entered directly into Radians.
